Pros
I've been working at Riot Games for just over two years now, and been in the games industry for ten years, across three different companies including Riot. All of the companies have their pluses, but at Riot, people really care about our players. The atmosphere at Riot, allows people to contribute from across different disciplines and even continents, to ensure that we are providing the best possible player experience out there. It's been a refreshing experience, to work with others that take the player experience to heart. I've been in the Sydney office since January, and the office is in a great location, within walking distance to all that the city has to offer. The team is small, hungry, and motivated. We are able to work without constraints, to create a great experience for our players here in Oceania. The office perks are exceptional, and Riot treats it's employees like family. Quick Points: Great, open feedback culture; Highly transparent and trusting of everyone that works here; Amazing perks that include a yearly trip; A team dedicated to ensuring that people are taken care of, and extending that to your family as well; Tons of learning and development opportunities; Challenges of scale, technology, and craft that will keep you sharp; Failure is ok, but learn from it and move on.
Cons
Nobody will stop you from taking on too much. I personally have a hard time saying no, and because of this, it was easy to take on more than I could chew, when I first started. You will work with people that are driven, people that work very hard, but work-life balance is important. It will be up to you to keep that in check.
